We first started out by classifying polynomials by the number or terms
- Monomial- polynomial with one term (ex. 10 or 14x)
- Binomial- polynomial with two terms (ex. x+2 or 4x^4-7x)
- Trinomial- polynomial with three terms (ex. x+2+3x^2)
(-y+6)(y^4+2y^2-3) first you must foil it by hand which we learned in some older chapters. when you foil that you get -y^6-2y^4+3y^2+6y^4+12y^2-18... then after you reduce that all down you end with -y^6+4y^4+15y^2-18.
But if you would rather not go through all that fun you can simply type it in to your calculator and get the answer fully reduced and without straining yourself in the slightest.
